Abstract

An amorphous FeCoNiBO_x catalyst is fabricated through low-temperature chemical-reduction, and exhibits remarkable oxygen evolution reaction (OER) electrocatalytic properties due to the synergistic effects of multiple elements, amorphous nanostructure, and in situ reconstructed surface with high activity triggered by borate leaching, which improves the electronic conductivity and provides abundant accessible active sites for OER.
